Novel prestressed steel strand
The invention belongs to the technical field of metal wires, and particularly relates to a novel prestressed steel strand. The novel prestressed steel strand is composed of a central wire and six side wires, and the sections of the central wire and the sections of the six side wires are each approximately hexagonal; and the six side wires surround the central wire to form a honeycomb shape. The novel prestressed steel strand has the advantages that holes between the wires are small, and meanwhile, the periphery of the prestressed steel strand is in a concave-convex shape; the adhesive strength between concrete and the prestressed steel strand is large, and the concrete is not prone to falling off; the overall tensile strength is greatly improved; and meanwhile the service life of the prestressed steel strand is prolonged.
